Understand

Chromospherically Active Binaries (CAB) catalogue have been revised and updated.

• With 203 new identifications, the number of CAB stars is increased to 409.
• Catalogue is available in electronic format where each system has various number of lines (sub-orders) with a unique order number.
• Columns contain data of limited number of selected cross references, comments to explain peculiarities and position of the binarity in case it belongs to a multiple system, classical identifications (RS CVn, BY Dra), brightness and colours, photometric and spectroscopic data, description of emission features (Ca II H&K, $H_{\alpha}$, UV, IR), X-Ray luminosity, radio flux, physical quantities and orbital information, where each basic entry are referenced so users can go original sources.
